Grease Fittings

Thread these fittings into motors, bearings, engine blocks, and other machinery to create a lubrication point. They’re also known as hydraulic grease fittings.

Straight with Male Thread

Zinc-Plated Steel—Zinc-plated steel fittings have mild corrosion resistance.

Brass—Brass fittings resist corrosion better than zinc-plated steel fittings.

303 Stainless Steel—303 stainless steel fittings are more corrosion resistant than brass fittings and have good chemical resistance.

316 Stainless Steel—316 stainless steel fittings resist corrosion and chemicals better than 303 stainless steel fittings and can be used in saltwater environments.

Ball Check Valve—Fittings with a check valve prevent grease from leaking when pressure causes backward flow. The valve stays closed when not in use to keep out dirt and other contaminants.

Grease Fitting Adapters

When the size or thread type of a fitting doesn't match an existing opening, use these adapters to make the connection.

Straight

NPTF Thread—NPTF (Dryseal) threads are compatible with NPT threads.

Brass—Brass adapters resist corrosion better than zinc-plated steel adapters.

Compact Pressure-Relief Valves

Due to their small size, these valves are often installed on tanks in low-clearance areas. They begin opening at the set pressure. Nylon valves fully open at about 10% over the set pressure and steel valves fully open at about 50% over the set pressure. Valves begin closing as pressure drops and fully close when the system pressure is restored below the set pressure. All have a vent outlet to exhaust discharge directly. Set pressure is not adjustable.

Adjustable-Flow Grease Dispensers

For more control over the flow rate of your grease, choose these gas-driven dispensers over spring-driven dispensers. Their continuous flow automatically adjusts based on the dispensing duration you set on their dial (from one to 12 months). Because you control when they’ll empty, these dispensers make it easy to plan maintenance. To prevent over-lubrication when your machine is down, turn the dial to zero to cut off flow without uninstalling the dispenser. They’re best for applications with consistent temperatures, so the viscosity of the grease won’t change how quickly it flows. All have a clear bowl so it's easy to monitor the grease level.

Rated IP68, these dispensers seal out dust and water from temporary submersion. They’re ATEX certified for use where explosive gases and dust could be present, such as mines and oil refineries.

Grease-Filled Dispensers


	Flow-Adjustment Time-Set Dial

Grease-filled dispensers are ready to go right out of the box, so they're faster to install. They eliminate the mess of filling and keep out contaminants because you throw them away when empty. Grease-filled dispensers also reduce the chance you’ll fill a lubrication point with the wrong grease.

Calcium Sulfonate Grease Thickener—Grease with a calcium sulfonate thickener has good heat resistance and excellent resistance to moisture and oxidation.

Lithium Grease Thickener—Grease with a lithium thickener offers good heat and moisture resistance.

Molybdenum Disulfide Lubricant Additive—Grease with a moly (molybdenum disulfide) additive has excellent resistance to wear and withstands high-load and high-pressure applications.

NSF Registered H1—NSF registered H1 dispensers come with grease that’s safe for incidental contact with food.

Cannot Be Sold To—Dispensers cannot be sold to the listed areas due to local regulatory limits on mercury content.
